1.Classification and causes of stains: </p
衣服在穿着的过程中，会受到来自内、外两方面的污渍沾污。污渍成因主要概括为四个方面：（1）穿着过程中浮游尘埃的污染；（2）汗液等分泌物的污染；（3）微生物的污染；（4）洗涤过程中的再污染等。

2.Easy decontamination finishing mechanism: </p
易去污(soilrelease)整理是使织物表面的污垢容易用一般洗涤方法除去，并使洗下的污垢不致在洗涤过程中回污的工艺过程� �织物在穿着过程中，由于吸附空气中的尘埃和人体排泄物以及沾污而形成污垢� �特别是合成纤维及其混纺织物，容易带静电吸附污垢，并由于表面亲水性差，洗涤中水不易渗透到纤维间隙，污垢难以除去� �又因织物表面具亲油性，所以悬浮在洗涤液中的污垢很容易重新沾污到纤维表面，造成再沾污� The basic principle of increasing the ease of stain removal of synthetic fibers and their blended fabrics is to use chemical methods to increase the hydrophilicity of the fiber surface and reduce the surface tension between the fiber and water. It is best that the hydrophilic layer on the surface can expand after being wetted. This generates mechanical force so that dirt can automatically leave �其方法是在织物表面浸轧一层亲水性的高分子材料� �易去污整理后，还可增加织物的抗静电性，穿着舒适，手感柔软，但织物的撕破强度有所下降� �</p
德科纳米事业部供应的FCK009易去污整理剂，不但具有易去污效果，而且有一定的防污效果，给织物全方位的呵护�
